Miley Cyrus Skydives, Flips The Bird In New Rolling Stone Clip

'I'm f---ing terrified!' Miley says before leaping 12,500 feet out of a plane for RS cover story.

Miley Cyrus goes all out in her new Rolling Stone cover story, getting the magazine's name tattooed on her feet, partying until dawn at a Hollywood club, admitting Steve Carell gives her the "stank eye" ... though there's one moment that stands above all the rest: when she decides to leap out of a plane 12,500 feet in the air.

And now, there's actually footage of Cyrus' death-defying skydive session. Rolling Stone had cameras on hand when Cyrus and her assistant/BFF Cheyne jumped out of a plane high above the L.A. desert — because why wouldn't they? — and after watching the video, we can definitely attest to the fact that Miley is a bad-ass.

In the video, she admits that she's "f---ing terrified," and as the plane begins to make its ascent, she even flips the camera the bird, declaring "f--- you, Rolling Stone magazine." Then, she jumps (it's a tandem jump, with an instructor on her back, but still) and as she plummets through the sky, she even manages a defiant tongue wag.

After her instructor pulls the cord on her parachute, Miley slowly drifts down to earth, surveying the scenery around her and declaring "I'm finally a bird, like I always wanted to be."

Of course, her session wasn't totally a success: when she lands, she's briefly trampled by her instructor, though she seems to take it all in stride, giving the cameras a thumbs-up and laughing "What a landing!"

How can Miley possibly top this? Why, with her own documentary, of course! "Miley: The Movement" premieres Wednesday, October 2 at 10 p.m. ET/PT on MTV ... tune in to see what she'll do next!
